Use-Chainlink-On-xDAIChain

Actively push offchain data to xDAIChain

Project Structure

This project is built with truffle init.

Basic Structure:

  • contracts
  • migrations
  • test
  • truffle-config.js

After truffle compile or truffle migrate, it will generate a directory which is called build and it is used for storing the ABI files of contracts.

I add the directory of client which stores the Node.js script to interact with contracts on xDAIChain and ethereum mainnet or testnet.

Goal

Get offchain data from Chainlink. Specifically, collect ETHUSD price from Chainlink PriceFeed.

Environment Setting

npm install @truffle/hdwallet-provider

RPC Setting inside networks section:

 sokol: {
      provider: () => new HDWalletProvider(privateKey, `https://sokol.poa.network`),
      network_id: 77,
      gas: 500000,
      gasPrice: 1000000000
    },
    xdai: {
      provider: function () {
        return new HDWalletProvider(
          privateKey,
          "https://dai.poa.network")
      },
      network_id: 100,
      gas: 500000,
      gasPrice: 1000000000
    },
